Grays to Rads
1 Gy = 100 rad. Edit either value to convert instantly.
Conversion formula
rad = Gy × (1) × (100)1 Gy = 100 rad
gray (Gy)
gray is a unit of absorbed dose. Absorbed dose is deposited radiation energy per mass; 1 Gy = 1 J/kg. It is distinct from equivalent dose in sieverts.
rad (rad)
rad is a unit of absorbed dose: 1 rad = 0.01 Gy. Absorbed dose is deposited radiation energy per mass; 1 Gy = 1 J/kg. It is distinct from equivalent dose in sieverts.
